Synthesis of 4-alkyl-1,2-diphenyl-3,5-dioxopyrazolidines possessing aryl methylsulfonyl and sulfonamide pharmacophores for evaluation as selective cyclooxygenase-2 (COX-2) inhibitors

A group of 1,2-diphenyl-3,5-dioxopyrazolidines possessing a methylsulfonyl (11) or sulfonamide (15) substituent at the para position of the N1-phenyl ring, in conjunction with a hydrogen, methyl or fluoro substituent at the para position of the
